DAEJEON, July 13 (Korea Bizwire) — A South Korean research team has developed an artificial sensory interface system that mimics the human body’s neural signals.
The system is expected to be able to be used in various areas, including virtual reality and the metaverse.
Scientists have struggle to develop an artificial sensory system that is perfect enough to emulate the human body’s sensory system due to the complexity of the latter’s operating principles.
Humans sense touch by combining information through various types of tactile receptors such as pressure and vibration.
A joint research team from the Korea Advanced Institute of Science and Technology (KAIST), Korea University and Hanyang University succeeded in creating a nanoparticle-based multi-tactile sensor that mimics the human tactile recognition process by connecting it with a signal conversion system based on actual neural patterns.
The research team developed an electronic skin by applying a piezoelectric material that can mimic simultaneously the two mechanoreceptors, one that can detect pressure in the skin and another that can sense vibration.
The researchers used the method of extracting actual sensory nerves, measuring signals from various senses and then functionalizing.
The research team created the sensory system in a fingerprint structure and carried out an experiment to classify about 20 types of fabrics. The experiment showed that the sensory system classified the fabrics with an accuracy rate of more than 99 percent.
